High Carbon Ferro Manganese | Cost-Efficient Manganese Base Alloy For Mass Ordinary Carbon Steel & Grey Iron Casting

1. Product Brief

High Carbon Ferro Manganese, generally shortened as HC FeMn in international metallurgical trade invoices, is mature manganese alloy independently smelted in submerged arc furnaces by Zemei Metal with two decades of ferroalloy manufacturing experience. This High Carbon Ferromanganese Alloy acts as cost-optimized Foundry Manganese Additive and mass-production focused Steelmaking Manganese Deoxidizer, also known as standard High Carbon Mn Ferroalloy for bulk low & medium grade steel and general grey iron manufacturing lines. Medium and low carbon manganese alloys feature low carbon content yet higher raw material expenditure; by contrast, HC FeMn maintains stable manganese concentration with controlled carbon scope, delivering balanced metallurgical performance while cutting overall purchasing costs for continuous mass production. Once injected into molten steel or liquid grey iron, manganese components within this alloy rapidly bind dissolved sulfur and residual oxygen, forming floatable manganese sulfide slag that can be fully skimmed off during ladle treatment. The treatment simultaneously completes deoxidation and manganese alloying, eliminating hot shortness flaws and lifting finished material hardness, tensile strength and abrasion resistance. This material is highly favored by medium and large smelting plants pursuing cost control without sacrificing core mechanical indicators. Zemei's self-built 10,000 square meter integrated smelting plant reaches an annual total ferroalloy capacity of 35,000 tons, split into submerged arc melting zone, water cooling crushing workshop, multi-layer vibrating screening station and high-precision ICP testing lab. Round-the-clock closed dust collection and waste gas purification systems ensure all emission parameters comply with global industrial environmental thresholds. We accept 1-ton small trial consignments and 25-ton full-container sea shipments, capable of adjusting manganese-carbon ratios and particle gradings according to clients' steel grades and casting wall thickness requirements. The enterprise holds complete ISO triple management certifications; each batch of HC FeMn comes with factory COA and SGS third-party element inspection papers, full audit and customs documents can be compiled for overseas import filing.

2. Fixed Chemical Index & Custom Particle Series

Stable element band of High Carbon Ferro Manganese: Mn 75–80%, C 6.0–8.0%, Si ≤2.0%, P ≤0.35%, S ≤0.04%. Two differentiated standard grades for different production conditions:

General HC FeMn (Mn75/C7): universal material for conventional carbon steel and regular grey iron casting

High-Mn HC FeMn (Mn78–80): dedicated alloy for low-alloy steel requiring elevated manganese content Four available particle specifications to match various feeding equipment: 10–100mm large lumps for blast furnace bulk feeding; 5–50mm medium granules for electric furnace ladle addition; 0.5–10mm fine grains for automatic quantitative feeders; 40–120 mesh fine powder for pre-alloy blending. Three-stage layered screening restricts floating ultrafine powder under 6%, lowering oxidation loss during stockpiling and conveying, manganese absorption rate inside molten metal exceeds 80%. Standard export moisture-proof packaging: double plastic inner lining, optional 25kg woven sacks or 1-ton PP jumbo bags, all secured on fumigation-free timber pallets with stretch film. Blank neutral packaging and customized pallet brand printing are supported; dual damp isolation film can resist oxidation damage during 2–6 months humid ocean transport. Every pallet undergoes random ICP sampling plus molten steel alloying simulation before delivery to guarantee consistent element indexes of each lot. Small trial batches starting at 1 ton are accepted without minimum order restrictions, sample payment can be fully deducted in subsequent full-container bulk cooperation. Adjustable custom items include manganese-carbon proportion and particle mesh size.

4. Global Exclusive Application Segments

Conventional carbon steel & low-alloy steel refining: primary manganese alloying agent and auxiliary deoxidizer, eliminating sulfur-induced hot brittleness and improving steel hardness & wear resistance.

General grey iron & lightweight low-demand nodular iron casting: economical Foundry Manganese Additive to boost casting mechanical performance and abrasion resistance.

Welding rod core alloy raw material: high-carbon manganese fine powder for welding formula adjustment.

Medium & small smelters mass deoxidation substitute: lower-cost alternative to medium carbon ferromanganese for continuous mass production.

Pre-blended composite ferroalloy raw material: matched with silicon alloy for integrated ladle molten metal treatment. Compared with medium carbon ferromanganese, adopting High Carbon Mn Ferroalloy can slash auxiliary raw material procurement expenditure by 18–26% for large-scale steel and casting manufacturers.

5. Six Distinct Product Competitive Strengths
